[Xen-devel] [OSSTEST PATCH 09/12] ts-guests-nbd-mirror: add checkaccessible test

[Ian Jackson <ian.jackson@xxxxxxxxxxxxx>]

If the NBD devices are not properly accessible on the client, bomb out
here rather than futilely starting a guest, and then timing out when
the guest fails to boot because it can't find its root fs.
